i used to have this problem back in the mists of time when i had two old ntl boxes i set both of the boxes as far back as i could on two shelves in the tv Cabinet that we had this meant there was a very narrow angle where the remote could affect the infra red sensor there by allowing us to choose which one was operated by the remote by angling it up and down .putting a shelf in between them jutting out would work just as well i would have thought ( if i havnt explained that very well i will try harder lol i will see if i can find a diagram )
